MyD88 standing for myeloid differentiation primary response 88 is a cytoplasmic adaptor protein with a molecular weight of approximately 33 kDa. This protein is expressed widely in immune cells including monocytes macrophages and dendritic cells. MyD88 serves a major role in the signaling pathways for the innate immune system. It acts as a linker transmitting signals from toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs) to downstream signaling molecules ultimately activating transcription factors.
Biological function summary

MyD88 plays a significant role in mediating immune responses by forming part of a complex that includes IRAK kinases and TRAF6. When TLRs or IL-1Rs activate MyD88 this adaptor protein recruits IRAK4 which then phosphorylates IRAK1 or IRAK2. This cascade promotes the activation of NF-κB and MAPK pathways leading to the production of inflammatory cytokines. The MyD88-dependent pathway is integral to innate immunity influencing how the body responds to pathogen infection and inflammation.

Pathways

MyD88 integrates into both the TLR signaling and IL-1R signaling pathways. Key related proteins in these pathways include interleukin-1 receptor-associated kinase (IRAK) and tumor necrosis factor receptor-associated factor 6 (TRAF6). MyD88 initiates the recruitment and activation of IRAK1 and IRAK4 following receptor engagement leading to subsequent activation of downstream signals. As part of these pathways MyD88 mediates cellular responses important for immune system signaling and inflammatory response regulation.

MyD88 involvement is notable in the context of oncological and autoimmune diseases. Mutations or dysregulation of MyD88 are implicated in conditions like lymphoma and rheumatoid arthritis. In lymphoma the mutation usually results in constant activation of NF-κB leading to unchecked cell growth. As for rheumatoid arthritis an overactive immune response due to MyD88 can cause additional inflammation affecting joint tissues. In these conditions MyD88 interaction with IRAK4 is significant given their mutual role in immune and inflammatory pathways.

Target data

Adapter protein involved in the Toll-like receptor and IL-1 receptor signaling pathway in the innate immune response (PubMed : 15361868, PubMed : 18292575, PubMed : 33718825, PubMed : 37971847). Acts via IRAK1, IRAK2, IRF7 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (PubMed : 15361868, PubMed : 19506249, PubMed : 24316379, PubMed : 40638072). Increases IL-8 transcription (PubMed : 9013863). Involved in IL-18-mediated signaling pathway. Activates IRF1 resulting in its rapid migration into the nucleus to mediate an efficient induction of IFN-beta, NOS2/INOS, and IL12A genes. Upon TLR8 activation by GU-rich single-stranded RNA (GU-rich RNA) derived from viruses such as SARS-CoV-2, SARS-CoV and HIV-1, induces IL1B release through NLRP3 inflammasome activation (PubMed : 33718825). MyD88-mediated signaling in intestinal epithelial cells is crucial for maintenance of gut homeostasis and controls the expression of the antimicrobial lectin REG3G in the small intestine (By similarity).
